1 0 all toil/om in TIMI/,7] concern:

Be it known that I, ALrnnn Rows BEL- Li\i1\=iY,-e11glIi el, a subject of the King oi Great Britain and Ireland, residing at lrordsbuig,

.lildgeley, titoclqiort, in the county of Chester,

'i higland, have invented certain new and use ful improvements 1n or Relating to Sparking lgniters for Internal Combustion Engines, (for which I have made an application in Great Britain, No. 19,428, dated the 9th day of September, 1904,) of which the following is a specification.

My invention has reference to electrical igniters applied to gas and similar internal-- combustion engines in. wl'iicl'i a current oi electricity is interniittently generated by the abrupt oscillation of e trip-lever connected to the armature of the magneto-electric gen When applied .to a stationary gas en gine, the tri -lcver in recent practice connected to a p unger or rod acting against e spring, the rod being arranged to monientw rlly withdraw a finger from the terminal or sparking plug within the combustioncham ber of the cylinder of the engine at the exact moment that a current of electricity has been induced Within the circuit by the oscillation. of the -.trip-lever,' and thus cause the current to leap the gap so for "red, producing a sparlr whiclii. tires the compre sod charge.

In the accompanying driiwings, Figur .11 shows inside elevation so much of an re retrical igniting device as is neces" comprehension. of my invention it proved means for actuating the t ip l? 2 is an ele in oi the same at i. gles to Fig. 1. i gs. 3 end 4-. are separate detail views of one of the parts of my invention.

My invention refers to means for effecting the oscillation of the trip-lever rt of the generating-n1achine at the required time, which consists as follows: On the side shaft 1) of the stationary gas-engine, part of the cylinder 0 only of which is shown inthe drawings, I mount an eccentric d and strap, the strap e having a rod f, which is connected at some part of its length to a link g, pivoted to a suite ably-shaped bracket B or iixed part of the engine. carries a tappet h, adjustaliile on the rod. AS the sheave oi the eccentric revolves with the side shaft 7) the upper end of the rod, owing The upper end oi the eccentric-rodf from it on the upward stroke. The eccentric and rod are so adjusted with respect to the trirelever of the i'nagneto machine A that on the downward stroke of the rod the tappet lb com cs into contact with the trip-lever a, vibrating it in a downward direction until re leased by the tappet. This movement of the tripdever (r raises the plunger i against the action of the upper spring '3 in the casing 7r. immediately the tappet 71 is withdrawn from the trip-lever a the upper spring 3', which has been compressed, gives a rapid reverse inovemerit to the trip-lever a and the spindle a, thereby generating a current of electricity within. the circuit. The lower spring 1 acts as a butter on this reverse stroke of the plunger On the consequent descent. of the plun .ger i the lever i is depressed, withdrawing the attached finger Z from the terminal in the coinbustionchamber of the engine, thus making a brake-spark and igniting the coinhustible mixture To regulate the oscillatien oi the trip-lever (1,, the link 9 may be mounted in bearings in the-frame of the engine adjustable toward or from the eccentricrod, so as to bring the tappet 7L nearer to or p he it farther away from the trip-lever a. This could i ing; the linlr. to an eccentric, the rotation of which would give the required adjustment. Tillie moons of accomplishing this is shown in detail in Figs, 3 and 4-.

ilhe bracket B or sui table fixed part of the engine is provided with a bearing m for a re tatable stud n, which carries an ecccntricallymounted pin 0, upon which is pivoted the end of the linlr 5 By rotating the stud n the requisite adjustment wan. be obtained. The ro tation of the stud n is effected by means of a handle or lever 71, secured to the stud nand normally loclred in position by means of a wedge (1, carried by the lever 12, and thrust by means of a spring into one of a series of notches or teeth 1', carried by the bracket B. By withdrawing the spring-actuated wedge the handle or lever 27 and with it the stud n can be rotated to the desired extent.
